Infant children{3 s shoe

ABSTRACT

In this infant children&#39;&#39;s shoe, cemented in some embodiments to the outsole of the shoe at a heel position, is the heel formed in a shape such as bounded by its inner lateral rim, rear rim and outer lateral rim extending forward on the outsole and also forward rim of arcuate concaveness. This shoe heel may either be attached by cementing directly onto the outer face of the outsole, or cemented to the insole through a part cut through at the heel position and in a shape in conformity with that heel shape.

PATENTED MAY 2 7 I975 SHEET DEDF 2 INFANT CHILDREN S SHOE BACKGROUND OFTHE INVENTION This invention relates to an infants shoe which is made bycementing the heel to the shoe sole. This shoe heel is formed in a shapesuch as bounded by its inner lateral rim, rear rim and outer lateral rimextending fOF ward from its rear part and also forward rim of arcuatceoneaveness.

When an infant child was wearing various conventional shoes which didnot readily give a stability to his standing posture, a normal movementof his center of gravity by walking motion was impeded, making his walkextremely unstable. Thus, he was liable to fall during the walk. Thiscauses the infant to have a fear complex from walking, getting himbehind the time to commence his walk. And if he is forced to walk withsuch conventional shoes worn, it is feared that the growth anddevelopment of his foot would be affected badly.

An object of the present invention is to provide an infants shoe thateliminates said disadvantage of the conventional shoes, thereby enablingthe infant child to take a natural and stable standing posture lest heshould be slow in commencing his walk, and in order that, through aposture like this, a normal growth and functional development of hisfoot is insured and promoted.

DESCRIPTION OF INVENTION RELATING TO DRAWINGS The construction of theinfants shoe of this invention will be clearly shown below byexplanation of the ac companying drawings.

Referring to the drawings of the infant childrens shoe of the presentinvention, FIG. 1 shows a perspec tive drawing relative to the firstembodiment of the present invention, as viewed diagonally from below;

Then, FIG. 2 is a drawing of the face of the shoe shown in FIG. 1;

FIG. 3 shows a cross-sectional view as made along the line A to A inFIG. 2;

FIG. 4 shows a perspective drawing of the second embodiment of theinfants shoe of the present invention, as viewed diagonally from below;

FIG. 5 shows a drawing illustrating the face of the sole of the shoeillustrated in FIG. 4; And finally,

FIG. 6 is a cross-sectional view as made along the line B to B.

In the embodiments illustrated in FIGS. 1 to 3, the whole of the outsolemember la and upper member lb is formed undivided and in one piece. Inthese embodiments of invention, the space for shoe heel is cut from theoutsole at the corresponding heel position, in a shape such as made byits inner lateral edge, rear edge and outer lateral edge extendingforward about halfway of the length of the outsole and also forward edgeof arcuate concaveness that runs from the front end of said innerlateral edge to the front end of said outer lateral edge.

All of these inner lateral edge, rear edge and outer lateral edge arelocated somewhat inward from the periphery of the shoe outsole.

The heel 2 to be attached is formed in a shape such that its innerlateral rim, rear rim, outer lateral rim and forward rim all wouldconform with the respective corresponding edges of the part as abovementioned of the outsole having been cut from it.

The insole 3 is cemented onto the back of the outsole, and the heel isinserted to the part cut through in a manner that its respective rimswould conform with the corresponding edges of the part of the outsolecut through, then it is cemented to the insole. Therefore, it comes thatthe inner lateral rim, rear rim, outer lateral rim and forward rim ofthe heel held in place, are in conformity with corresponding innerlateral edge, rear edge, outer lateral edge, and forward edge of thepart cut through of the outsole, respectively.

In these embodiments, the shoe outsole la is cut through so that theheel 2 of the shoe would be placed in position through the part cutthrough for cementing. However, in the stead of doing so, the heel maydirectly be cemented onto the exterior side of the outsole.

In this invention, it is not necessarily specified that the whole of theoutsole member and the upper member is continuous in making. These twomembers may also be assembled together by stitching or cementing.

Next, the second category of embodiment will be described below,referring to FIGS. 4 to 6;

The insole member 11a and upper member llb of the shoe are madecontinuous and in one piece. The outsole member 13 is cut through sothat the forward edge of arcuate concaveness running from the outerlateral edge that extends about halfway forward on this shoe outsole, tothe inner lateral edge is provided to the shape of the cut through part.Here, said inner lateral edge, rear edge and outer lateral edge areprovided somewhat inward from the corresponding part of the periphery ofthe shoe outsole. Said outsole member is cemented onto the exterior faceof the insole member 1 la.

The heel 12 is formed in a shape bounded by its inner lateral rim, rearrim, outer lateral rim and forward rim, every one of which will conformwith the respective corresponding edge of the cut-through part of theoutsole member.

Said heel is placed in position through the cutthrough part of theoutsole member in a manner that its every rim will be in conformity withthe respective corresponding edge of the cut part, and is cemented tothe insole member.

Alike the preceding embodiment category, in these embodiments, the heelmay directly be cemented to the outsole member, in the stead ofinserting the heel through the part cut through the outsole member atthe heel position and cementing it to the insole member. Besides, theshoe must not necessarily be made so that the whole of its outsolemember and upper member are continuous, that is to say, these twomembers can be stitched or cemented together.

In the infants shoe of the present invention, how much the heel 2 or 12in its respective case would be lofted from the outsole member 3 or 13,i.e., the actual heel elevation is not particularly confined. However,the adequate elevation is about 0.5 to 1.0 mm. Besides, the material ofsaid heel is not limited to a particular substance. However, in view ofthe heel being for the infants shoe, natural or synthetic rubber ispreferable for slip-proofing purpose.

Furthermore, any substance suitable can be used for making the shoe ofthe present invention. Non-woven fabric or cotton fabric can be usedother than leather.

Since the infant childrens shoe of the present invention is constructedas described above, due to some 0.5 to 1.0 mm elevation of the foot soleof the part located above the shoe heel of the invention. weight andforce works on such elevated part of the foot sole more than on otherpart thereof, whereby while an infant is standing or making foot steps,with this shoe being worn the foot can be prevented from staggeringoutward. This. at human beings most important period from the time ofstanding straight to the time to commence walking. as well helps himstand in a natural and stable posture and promotes a development of hisnormal foot functions as enables him to make an accurate and safe footstep motion. Furthermore, the heel appearing exposed from the shoe soleworks as a mark for identification of the shoe, thereby making it easyto find the shoe of the purpose of this invention at a retail shop. And,finally the shoe has an additional advantage of having said heel whichworks as a slip-proofwhile wearing it. These are extremely unparalleledadvantages of the referred shoe.
